2011 Borlaug LEAP Fellow Armand Doumtsop wants to find practical solutions to the problem of ARTS (African root and tuber scale). Tropical root and tuber crops are major staples in sub-Saharan Africa. These crops are largely produced by smallholder farmers.  Pests, such as African root and tuber scale (ARTS), are a major threat to farmer’s livelihoods. The economic consequences are serious in the Congo Basin where it can cause cassava yield losses of up to 100%.
